Power Trim & Tilt troubleshooting 1987 OMC, Johnson, Evinrude 90HP V4

A digital multi meter is strongly recommended. The Fieldpiece SC260 is my favorite. (ebay) This is a general look at the electrical part of the PT&T system on an OMC outboard motor. This general setup will be similar to all this era outboard motors. The advice applies to all motors. If your trim motor runs but nothing happens, check the fluid in the reservoir. Mine uses Dextron Automotive transmission fluid. Look yours up. It will be listed on the net somewhere. Also remember, the press. relief valve which is that screw on the right side. If it's not tight, the system won't pressurize and the motor will not move. Make sure that your motor is not seized on the tilt tube as well. I put a nice stainless steel one on this motor a few years ago. You should be able to unscrew that relief screw a turn or 2 and lift the motor by grabbing it by the skeg below the prop. If you can't, you will need to cure that issue 1st. Remember, if in doubt, clean all the electrical connections and try to find all connectors. Those are the weakest points in any electrical circuit. Boating season is rapidly approaching! Good luck.

If you want to help me with my retirement, please consider donating to my retirement fund. There’s a {$} sort of symbol up there on the right or a “thanks” button.. Pressing that button activates the Super Thanks and allows folks to donate, or Buy Me a Coffee: buymeacoffee.c..., or here is a link to my Paypal account where you can send me whatever amount you might want. www.paypal.com.... Any amount will be greatly appreciated. It would be great to be able to actually buy a project that’s not on it’s last legs, or have to rely on whatever I can salvage. Thanks for watching either way.
Have a great day. Keep in mind, if I can do it, you probably can too.
